the moment you say something, I have a question in my head, but the very next sentence you speak answers that question immediately. You're an amazing teacher, I really appreciate all the effort you put into making this accessible to all of us. Thank you for giving me that confidence!
sm1 pls help.idk y i cant understand smthin. i expect the current to slow down after it passes thru the resistor but its the same thoughout the whole circuit.My brrain cant comprehend😭
The most lucid and clear explanations of basic electrical and electronic components i have ever attended online or offline in my career spanning 30 years.
I love how he emphasis a lot on important concepts using analogies. When I was studying electronics back in the old days, I accepted a lot of concepts the way it is and not really understanding why. After watching these videos, I.m going,...now I understand.
I am currently doing an online course to get an HVAC certification and I wasn't able to fully understand the textbook material but now that I've found your channel I'm already geeling like an expert. Great work man! Amazing teachings.
I am training to become a USPS Maintenance Mechanic for the mail machines and I have to cram everything about Electricity within a short period of time. Feeling overwhelmed. But after watching this video I’m starting to feel a lot more confident. He’s such an AMAZING teacher! He breaks it down with examples and multiple explanations repeatedly! Exactly what I was looking for! Now I don’t feel like an idiot for not understanding this. LOL 😂 Thank you so much!! 🙏
I ran into this playlist trying to brush up on electronics after not having done much with it since high school decades ago. This guy is a _fantastic_ teacher, thanks so much!
I'm not even studying electricity or anything related but it's always nice to have this kind of knowledge. I find these videos very enjoyable. Science is beautiful
I've been currently studying electronics for a few months and i watched 3 topics continuesly. It's just review to me but i learn a lot with this topics. I will watch more the continuation.. thank ypu very much for your clear explanation. Be blessed

My God, you are the best greatest teacher on earth, I don't know if there is or not anyone else that I know that teaches so clearly in detail, you should be an example to the entire world's education systems this is how everything should be taught , instead of long boring lectures, or reading books that are so hard just to understand what they are trying to tell you, because the way books are written is very official language which I abhor, a simple concept that can take one minute to understand takes hours, because the way these evil books are written , the concepts of science, math and everything else are not hard to learn and are actually fun to learn, if it wasn't for these official languages that are used in all books, I am so sick and tired of them. This is how everything should be taught in all schools. Simple, fun and clear. They should learn from you, you are the best and made a big difference in my life, truly American teachers are the best too at teaching. But offcourse your ways of teaching makes it the 👌 best.

@@ajscain500 so I’ve never found a book for “dummy’s” so to speak, however as I’ve progressed in my career here are a few things I could say to someone starting out in aviation. As a pilot it’s important to know what you can affect from the cockpit. While knowing your aircraft in and out will make you a more complete aviator keeping it simple to begin with will create the base you need to dive further. Start with your emergency procedures that deal with either alternator or generator issues. Be sure you can conduct the steps in the cockpit even if you don’t understand what’s happening behind them. As you progress, go through the operators manual and find the section that deals with the electrical system and components. From here identify what does what. Like “what does an alternator do?” Then what does an alternator do for my aircraft when it’s running then when it’s not. Keep in the operators manual page by page and look up things you don’t understand within the electrical system. Like a short circuit or a bad ground. Take it slow and you’ll be able to electricity in time, and most importantly how it affects you when something fails. I also highly recommend becoming your own mechanic.

I learned more in 10 minutes listening to you then four months of a semester an electrical class until you are my hero and thank you so much do you have a gift
Good day am from trinidad.About 30 years now i am trying to learn electronic,i know i have a memory problem but when i came across this teacher he explain things very simple i wish i had found him years ago ,he,s the best
I studied Electronic Engineering for 2 years at a college, yes I admit that i was young, easily distracted and uninterested at the time I was studying there. I somehow passed the course. But I've learnt more in this video than I did before. the difference is that he tells you why you would want to do this! My tutors just told you how and didn't give it any context! This Guy is a great Teacher! Thank you for creating this video series!
I am going to go ahead and get a subscription to stay busy throughout the holidays until my semester starts. Your teaching is just outstanding, I’m glad I found your classes.
My field is chemistry and I had a hard time for a long time learning about circuits!! This video was the best one! I love the method that you have for teaching!!!
I love the way you explain everything in your lessons! Sir, you are above any other teacher I have seen in my life. You are unique teaching science!!! I want to own your curses. God gives you long LIFE. Tank you so much!
Your analogys and ability to not go off on one and keeping it on track and simple are the reason (for me anyway) that make you easy to follow and understand. I've watched many videos before you that are supposed to be the basics but they can't stick with being simple,its a talent that makes a great teacher. Thank you :) I've bought some basic electronics packages to try these things out in practice.
The presenter has been very brilliant and a superstar with his wonderful coaching and explanations about how to read and understand what electrical circuits and components really are almost for nothing besides my data usage which was not for free...
This fella has excellent teaching techniques! Despite knowing /understanding Ohm's law from many years experience his presentation style keeps it interesting. So glad I stumbled across this channel. 😁👍
When talking about the voltage drop in the first couple of examples you talk of it like its something different from the voltage source, but its the same amount. I think this makes it a bit more confusing.
why??? the resister ABSORB it..so whatever is left over. You know....like a dimmer knob or POT...which is just a variable RESISTOR..You know....when the knob is at Zero...it has crapload of RISISTANCE..when it's on 5....it has you know 2 ohm . When you crank it all the way up on 10...it has Zero ohm. Different ACTIVE components has different voltage requirements...You basically use resistors to adjust to different component input...such as an LED is only 3v .if you had a 6v source...you'll need to drop it to 3v into the LED.......but the motor is still using 6v. or lets say..you had 8-12V esc for a motor...made in china. People say the fan keeps crappy out becuase it cant handle the 12V...becuase there's only a 1v-9v cooling fan. You can install a resistor to the fans input to drop it's into voltage to below 9V...instead of disconnecting the fan to save the fan ( which will kill your esc..lmao)
So for people that don't know, he offers the full course online and are amazing. It's 20 bucks if you do month to month. If you want to go back to school but don't want to take math classes again and want to test out, I highly encourage it. Either way, I'm just glad he makes some courses free because unfortunately we all didn't have a good education growing up
i see the general flow but 1. how does the current remain the same? i thought the resistor acted to constrain the flow of current? shouldn't it decrease after the resistor constrains it? aren't fewer electrons flowing after the current goes through the resistor? 2. if the measured voltage across the resistor is described as a drop in voltage does that mean the the resistor has absorbed energy from the battery? does this manifest as heat?
I was wondering the same thing but i think these examples are perfect scenarios in which the battery never runs out of charge (through heat - like u said) I imagine resistance as running through the street normally, struggling through sand, then back to the street. At the end you still ate 2500 calories but you burned maybe about 60 in a small circuit. And now your left with (2440 calories) btw Calories = HEAT (related to "calor" or heat in spanish)
Resistor acts as a filter in a way, it filters energy out of the circuit (and dissipates it, it is warm/hot to the touch as it does it). As the law of energy preservation states, if work is performed the energy of the system (circuit) decreases (to paraphrase it), the work being "fighting that resistance" + heat. That means the available energy for pushing the current AFTER the resistor is less (ie voltage drop). Power is P = V * I (don't confuse with Ohm's law), energy is P * t (time).
@@vyarovoy that makes a lot of sense. i guess the fact that the current remains constant throughout the entire series circuit is due to the affect of ALL the resistance.
I know that's weird to me too but after googling i understand it: Forget ohm law in this case Current is constant in a series circuit. Example current is the same after R1 R2 R3 Voltage is constant across parallel circuits. www.electronics-tutorials.ws/resistor/res_3.html
I come from a law and social science background, but after having watched your tutorial, I feel like I have learned more about electronics and electricity.
I dont quite understand. How can the voltage going down the resistor be the same at the beginning of the resistor and the end of the resistor. In other word wouldn't the voltage that is before the resistor be higher before it hits the resistor and go lower after the resistor?
Candice Jones no mate purely because it was a simple circuit with 1 resistor I.e a 1 load ( could be anything) which is basically neutral you probably know if you measure between live and neutral you will get 240v in the UK So that's basically why .ohms law is pretty easy to understand really it's only a it bit of algebra . But when you start getting in to micro circuits and and pcb builds it's a different ball game diodes, capacitors, transistors,Inductors,that's what he was getting towards on the other circuit he drew . But the maths is always the same ✌✌✌
Candice Jones When you put a voltmeter across the 1st resistor, you are measuring the voltage drop. Try putting a positive probe at the bottom of R2 and put a negative probe to ground, you will get 0 volt because the bottom of R2 is basically connected to the negative of the supply voltage.
Candice Jones The split second current hits the resistor, no voltage drop occurs. But when the current has 100% finished going through the resistor then. The voltage drop occurs.
Had R1 being 2 ohms and R2 also 2 ohms, the value of V1 is 8. I am wondering what would the value of V2 be? By using Ohms law, we get V2= 8 (that is, 4 *2). If we add V1 and V2, we get 16 = (8+8) whereas the original voltage was only 12. What am I getting wrong? For instance, shouldn't the current flow between R1 and R2 reduce to 2 or something like that.
My stumbling on to these lessons has been God sent. I am a DIY enthusiast wanting to learn to add sockets spurs on a ring. I have a few questions but feel this right here is not the appropriate forum. Would love to be able to place questions to one of the best teachers I have come across.
One of the best teachers on the net - so glad I found someone who can speak clear English - too many Indian tech guys out there that can’t speak well in English. Here’s a like an a subscribe.
Sir, you are the best instructor I have ever met. I want to do computer engineering with low math and physic skills but from your explanation as clear as it is, I can be a good student if I continue to watch your tutorials. Thank you ever so much.
Great job explaining the mysterious 'circuit drop' which baffles many. Probably because no one took the time to really explain it completely as it is here! Thanks!
Brilliant.. All through high school I struggled without understanding potential drop... This guy guy clears everything in less than an hour. Thanks very much.
This is the future of education and training of any subject even for the poorest thanks to you-tube. The best and most talented teachers can video lessons and any student in the World with a cheap old PC connected to the internet can learn almost anything from the best. Colleges and Universities could become obsolete. The teachers can distribute their lessons directly without needing a classroom and get rewarded via you tube. First learn English as it is the Worlds common business language and the World needs a common language.
I greet the great engineer,the epitome of knowledge,one of the greatest scientist ever in UA-cam after Lewin I wish I am able to afford the rest of your videos most especially in wave part of the physics, much love from Nigeria!
These are so helpful. I always wanted to be an astrophysicist but struggled in high school and thought I couldn’t but it was really just the teacher. I became a nurse instead but I’m burned out from the pandemic and going to revisit my childhood dream. Thank you for providing these to the public I cannot explain how much it means to have them available! It had given me confidence that i can do it. Looking back, these are just simple algebra and I’m not sure why I struggled with circuits so bad but it must be because you’re such a good teacher!
You are welcome! You know, it isn't too late for you to chase your dream! I snooped around and watched one of your youtube videos on space and your telescope. Many people don't have your passion - I just wanted to encourage you. It might seem like you are too old but you seem young and it might be too late to go back and get another degree and pursue your passion. I earned my last degree some time in my mid 30s. Take care! Jason
Just can't believe , I am experiencing this amazing explanation free of cost .....It's a gift to me that I found this channel......

I have taken many courses and saw many professors/instructors, but never like this one, truly amazing.
I really like this method of teaching.
I AM A TEACHER AND THIS GENTLEMAN IS TEACHING FROM HIS HEART.
Great teacher!! That why I’m back after two years. To Refresh my memory
I am an amateur radio enthusiast and this is one of the best ever ohms law explanations iv seen 👌
After an exponential amount of time, I’ve got it. Thank you! 👍🏽🙏🏼
I learned more in 10 minutes listening to you then four months of a semester an electrical class until you are my hero and thank you so much do you have a gift
you truly are a MASTER, Sir! Thank you! "If you can't explain it simply, you don't understand it well enough" -Albert Einstein.
I wish I could have met E = mc2. I’d like to spend the day with this guy too.
A gift we'll used. You have a gift of teaching, keep using it to better mankind. Thank you Sir, I salute u.
i am trying to get into electronics. and your course has been very helpful as a pre-study resource.
Good day am from trinidad.About 30 years now i am trying to learn electronic,i know i have a memory problem but when i came across this teacher he explain things very simple i wish i had found him years ago ,he,s the best
Excellent lessons. Thank you for taking the time to teach others!!!!
I studied Electronic Engineering for 2 years at a college, yes I admit that i was young, easily distracted and uninterested at the time I was studying there. I somehow passed the course. But I've learnt more in this video than I did before. the difference is that he tells you why you would want to do this! My tutors just told you how and didn't give it any context! This Guy is a great Teacher! Thank you for creating this video series!
This series is awesome. Thank you so much for uploading.
I am going to go ahead and get a subscription to stay busy throughout the holidays until my semester starts. Your teaching is just outstanding, I’m glad I found your classes.
Really this is the best explanation, before this video, I'm warning for my exam but now I understood well, thank you so much sir
My field is chemistry and I had a hard time for a long time learning about circuits!! This video was the best one! I love the method that you have for teaching!!!
I love the way you explain everything in your lessons! Sir, you are above any other teacher I have seen in my life. You are unique teaching science!!! I want to own your curses. God gives you long LIFE. Tank you so much!
Your analogys and ability to not go off on one and keeping it on track and simple are the reason (for me anyway) that make you easy to follow and understand. I've watched many videos before you that are supposed to be the basics but they can't stick with being simple,its a talent that makes a great teacher. Thank you :) I've bought some basic electronics packages to try these things out in practice.
today i have found my last stop where i can study everything of my life.God bless this tutor and his families all
What does god have to do with the current change in your life?
I never leave comments but you are the most amazing teacher ever wow ! You truly have a gift thank you so much !!!!!
I also love the fact that you remind us of certain concepts such as the voltage drop across. Really helps engrave that in my head
Indeed this is the greatest teacher ,,,,i love the explaination because it is very clear
I'm training to be electrician these videos are brilliant to help learn the basic circuits and ohms law.
Thank you this is exactly what I was looking for.
The presenter has been very brilliant and a superstar with his wonderful coaching and explanations about how to read and understand what electrical circuits and components really are almost for nothing besides my data usage which was not for free...
What a great teacher ... it's much like me, a blind guy seeing the entire movie in my mind.
Where is Lesson 4 ?
شكراً لك يا استاذي, يعلم الله انك افضل من شرح جزئية الكهرباء ومكوناته. افدتني كثيراً !
you're an angel. thank you.
This fella has excellent teaching techniques! Despite knowing /understanding Ohm's law from many years experience his presentation style keeps it interesting.
So glad I stumbled across this channel.
😁👍
Sir i'm sow happy to fined your page and it give me hope that i keen study electrical for free. god bless you.
Great teacher of all times. I am hooked on
Thank you for explaining it really clearly. Can you also talk about series and parallel ?
For as simple as ohms law is it is a head scratcher for sure. Need to watch this again. Thank you for your much needed help.
Damn you are so great! if I had such a teacher during school or college, I would rather be an engineer at least!
God Bless this Professor who actually took the time and explaining everything very well cause this is very helpful🙏🏻
When talking about the voltage drop in the first couple of examples you talk of it like its something different from the voltage source, but its the same amount. I think this makes it a bit more confusing.
Thank you. I was getting a bit confused.
why??? the resister ABSORB it..so whatever is left over. You know....like a dimmer knob or POT...which is just a variable RESISTOR..You know....when the knob is at Zero...it has crapload of RISISTANCE..when it's on 5....it has you know 2 ohm . When you crank it all the way up on 10...it has Zero ohm.
Different ACTIVE components has different voltage requirements...You basically use resistors to adjust to different component input...such as an LED is only 3v
.if you had a 6v source...you'll need to drop it to 3v into the LED.......but the motor is still using 6v.
or lets say..you had 8-12V esc for a motor...made in china.
People say the fan keeps crappy out becuase it cant
handle the 12V...becuase there's only a 1v-9v cooling fan.
You can install a resistor to the fans input to drop it's into
voltage to below 9V...instead of disconnecting the fan to save the fan ( which will kill your esc..lmao)
So for people that don't know, he offers the full course online and are amazing. It's 20 bucks if you do month to month. If you want to go back to school but don't want to take math classes again and want to test out, I highly encourage it. Either way, I'm just glad he makes some courses free because unfortunately we all didn't have a good education growing up
i see the general flow but 1. how does the current remain the same? i thought the resistor acted to constrain the flow of current? shouldn't it decrease after the resistor constrains it? aren't fewer electrons flowing after the current goes through the resistor? 2. if the measured voltage across the resistor is described as a drop in voltage does that mean the the resistor has absorbed energy from the battery? does this manifest as heat?
I was wondering the same thing but i think these examples are perfect scenarios in which the battery never runs out of charge (through heat - like u said) I imagine resistance as running through the street normally, struggling through sand, then back to the street. At the end you still ate 2500 calories but you burned maybe about 60 in a small circuit. And now your left with (2440 calories) btw Calories = HEAT (related to "calor" or heat in spanish)
Resistor acts as a filter in a way, it filters energy out of the circuit (and dissipates it, it is warm/hot to the touch as it does it). As the law of energy preservation states, if work is performed the energy of the system (circuit) decreases (to paraphrase it), the work being "fighting that resistance" + heat. That means the available energy for pushing the current AFTER the resistor is less (ie voltage drop). Power is P = V * I (don't confuse with Ohm's law), energy is P * t (time).
@@doctorluz180 Current is constant in a series circuit. Voltage is constant across parallel circuits.
@@vyarovoy that makes a lot of sense. i guess the fact that the current remains constant throughout the entire series circuit is due to the affect of ALL the resistance.
I know that's weird to me too but after googling i understand it:
Forget ohm law in this case
Current is constant in a series circuit.
Example
current is the same after R1 R2 R3
Voltage is constant across parallel circuits.
www.electronics-tutorials.ws/resistor/res_3.html
I come from a law and social science background, but after having watched your tutorial, I feel like I have learned more about electronics and electricity.
I dont quite understand. How can the voltage going down the resistor be the same at the beginning of the resistor and the end of the resistor. In other word wouldn't the voltage that is before the resistor be higher before it hits the resistor and go lower after the resistor?
go back to the video and start at the 17:00 minute mark. Hope this helps...
Candice Jones no mate purely because it was a simple circuit with 1 resistor I.e a 1 load ( could be anything) which is basically neutral you probably know if you measure between live and neutral you will get 240v in the UK So that's basically why .ohms law is pretty easy to understand really it's only a it bit of algebra . But when you start getting in to micro circuits and and pcb builds it's a different ball game diodes, capacitors, transistors,Inductors,that's what he was getting towards on the other circuit he drew . But the maths is always the same ✌✌✌
Candice Jones When you put a voltmeter across the 1st resistor, you are measuring the voltage drop. Try putting a positive probe at the bottom of R2 and put a negative probe to ground, you will get 0 volt because the bottom of R2 is basically connected to the negative of the supply voltage.
Candice Jones The split second current hits the resistor, no voltage drop occurs. But when the current has 100% finished going through the resistor then. The voltage drop occurs.
Had R1 being 2 ohms and R2 also 2 ohms, the value of V1 is 8. I am wondering what would the value of V2 be? By using Ohms law, we get V2= 8 (that is, 4 *2). If we add V1 and V2, we get 16 = (8+8) whereas the original voltage was only 12. What am I getting wrong? For instance, shouldn't the current flow between R1 and R2 reduce to 2 or something like that.
You deserve more than thank you sir. You helped me alot.
Even a child can understand. Teachers with Phds and masters have little or no skills of representing lessons to students
This guy is great at teaching this stuff. I had no prior knowledge but this makes so much sense
Where do I continue from now ? where is the next video?
Johnny Minter
Go to MathTutorDVD's playlist and it's under the "Engineering Circuits - Vol1"
Thank you so much!
Finish this, you are graduate .
My stumbling on to these lessons has been God sent. I am a DIY enthusiast wanting to learn to add sockets spurs on a ring. I have a few questions but feel this right here is not the appropriate forum. Would love to be able to place questions to one of the best teachers I have come across.
I'll be back , when I finished studying the spanish and German languages
One of the best teachers on the net - so glad I found someone who can speak clear English - too many Indian tech guys out there that can’t speak well in English. Here’s a like an a subscribe.
I never understood Ohm's law but in this lecture everything is clear as water
Not just water, but clean water
Sir, you are the best instructor I have ever met. I want to do computer engineering with low math and physic skills but from your explanation as clear as it is, I can be a good student if I continue to watch your tutorials.
Thank you ever so much.
Great job explaining the mysterious 'circuit drop' which baffles many. Probably because no one took the time to really explain it completely as it is here! Thanks!
Brilliant.. All through high school I struggled without understanding potential drop... This guy guy clears everything in less than an hour. Thanks very much.
What an absolute legend! Great teacher and so easy to follow!!! All the way from Scotland!
this is the best lecture I have ever received on ohm's law.
This is the future of education and training of any subject even for the poorest thanks to you-tube. The best and most talented teachers can video lessons and any student in the World with a cheap old PC connected to the internet can learn almost anything from the best. Colleges and Universities could become obsolete. The teachers can distribute their lessons directly without needing a classroom and get rewarded via you tube. First learn English as it is the Worlds common business language and the World needs a common language.
I greet the great engineer,the epitome of knowledge,one of the greatest scientist ever in UA-cam after Lewin I wish I am able to afford the rest of your videos most especially in wave part of the physics, much love from Nigeria!
I have recently had to learn Ohms law for a basic exam, thank you so much for an easy to follow guide.
Welcome!
Valeu!
Great teacher of theory, application, analysis of the circuit that anyone understand .❤
These are so helpful. I always wanted to be an astrophysicist but struggled in high school and thought I couldn’t but it was really just the teacher. I became a nurse instead but I’m burned out from the pandemic and going to revisit my childhood dream. Thank you for providing these to the public I cannot explain how much it means to have them available! It had given me confidence that i can do it. Looking back, these are just simple algebra and I’m not sure why I struggled with circuits so bad but it must be because you’re such a good teacher!
You are welcome! You know, it isn't too late for you to chase your dream! I snooped around and watched one of your youtube videos on space and your telescope. Many people don't have your passion - I just wanted to encourage you. It might seem like you are too old but you seem young and it might be too late to go back and get another degree and pursue your passion. I earned my last degree some time in my mid 30s. Take care! Jason
@@MathAndScience thank you I appreciate that so much!!
